Is the pentax k 70 good for wildlife?
Yes, the K-70 is a sensible body for wildlife, largely because of the lenses you pair with it. It has a 24.2-megapixel APS-C sensor and in-body stabilisation, and its 1.5 crop factor adds reach: a 300mm lens frames like 450mm on full frame.
For fast-moving subjects, the Pentax HD D FA* 70-200mm f/2.8 ED DC AW gives you a wide aperture and a useful range. When you need more distance, the Pentax HD D FA 150-450mm f/4.5-5.6 ED DC AW reaches much further.
Wildlife is the most gear-dependent kind of photography, so the lens matters more than the body. The wildlife and sport guide covers what to look for.
